RUDDER FOR HARROWS.

SPECIFICATION forming' part of Ietters Patent N0. 291,906, dated January 15, 1884:.`

Application filed August E23, 1883. (No model.)

To aZZ whom t may concern.-

Be it known that I, WARREN W. HILL, a citizen of the United States, residing at Texas, county of Kalamazoo, State of Michigan. have invented a new and useful Rudder for Harrows, of which the following is a specification.

My invention has for its object certain iniproved means, hereinafter described and claimed, for preventing the teeth of a barrow from trailing, by causing the frame or beams to which the teeth are attached to draw straight ahead in a given plane, and not move back and forth laterally during the operation.

In the drawings forming a part of this speciiicaton, Figure lis a top view of one wing of a butterfly-barrow frame, and Fig. 2 is a broken portion of the frame enlarged, showing a rudder connecting therewith.

B D are the beams composing the frame of a harrow. In the drawings here shown curved spring-teeth a a are connected with the frame in the usual manner of such style teeth and frame. It is especially with reference to said style of harrow that iny rudders are constructed; but they may be used with equal utility with other styles of loat-harrows, and with sulky-harrows and wheel-cultivators as well.

The rudder consists of ablade-shaped piece of steel or other suitable metal, c, having a rounded or runner-shaped sharpened edge presented to the soil. The top ofthe rudder has a series of holes, through one of which it is bolted to the frame, or, as in the present case, to a support, r, which is mortised at one end, and adapted to i'it the frame, to which it is bolted. The other holes in the rudder are used to adjust it higher or lower. When used with a butterliy iioat-frame, Fig. 1, I use two rudders on each half of the frame at the side.

In the operation the rudders enter the soil, and prevent any lateral swinging of the frame. As the rudder is fastened to the frame with a single bolt in the corner, where two beams, B D, cross each other, the rudder cants back until the back side intercepts the beam B in the rear at S, thus giving it a proper angle to draw easily, and holds it in said position.

Having thus described my inveution,what I l WARREN W. HILL. Vt-nesses:
